You can also include CSS elements internally by using the <style>
tag:
<head>
<style type="text/css">
body {
background-color: gray;
}
</style>
</head>
Multiple internal stylesheets can be included in a program as well.
<head>
<style type="text/css">
body {
background-color: gray;
}
</style>
<style type="text/css">
p {
background-color: blue;
}
</style>
</head>
